Root Cause Analysis
The vulnerability stems from how machine identifiers were generated in Docker environments. The pre-patch version of _generate() in get_machine_id() used system files that are identical across containers, creating insufficient entropy for debugger PIN generation. The commit 00bc43b specifically modified this function to check /proc/self/cgroup for Docker container IDs first, demonstrating this was the vulnerable code path. The CHANGES.rst update confirms the debugger pin uniqueness was addressed specifically for Docker containers in this function.
